EDIVARD PAYE, OF NEWY YORK, N. Y., ASSIGXOR TO I-IIMSELF AND CORNELIUS H. DELAMATER, OF SAME PLAGE.

FORGE-HAMMER.

Specification of Letters Patent No. 30,343, dated October 9, 1860.

T o all whom it may concern:

Be it known that I, EDWARD PAYE, of the ments in Forge-Hammers; and I do hereby declare that the same are described and rep resented in the following specification and drawings.

To enable others skilled in the art to make and use my improvements I will proceed to vdescribe their construction and operation,

referring to the drawings, in which the same letters indicate like parts in each of the figures.

Figure l, is a side elevation of a hammer with my improvements. Fig. 2, is a plan or top view of same.`

The nature of my invention and improvements, consist in an elastic or yielding connecting rod to operate the hammer. And in connecting one end of the connecting rod to a vibrating arm or lever to work the hammer. Also in connecting the connecting rod to the arm or lever which operates it, by means of a slide arranged to traverse on said arm, so as to vary the length of the stroke, and the force of the blows struck by the hammer while it is in operation. And in operating the arm or lever which works the hammer by a crank. And in balancing the helve and hammer by springs arranged either above or below the helve, on one or both sides of the fulcrum of the helve.

In the accompanying drawings A, is t-he base or bed to which the anvil block B, and stands C, C, are fastened, which stands may be made in the form shown or in such other form as will answer the purpose. The stands C, C, are perforated for the journals of the axis of the helve D, which has the hammer D fastened to it as shown in the drawing.

D2, is the anvil on which the metal to be hammered is laid.

Having pointed out the parts which are old and well known, I will now proceed to describe the improvements which I have invented.

The stands C, C, are perforated some distance below the aXis of the helve, for the journals of the crank shaft E, which shaft is provided with a fly wheel F, and pulley G, as shown in Fig. 2, for the belt which is to turn the crank shaft and operate the hammer. The crank of the crank shaft is l arranged midway between the stands C, C, and is connected by the link H, to the lever I, as shown in Fig. 1.

The lever I, is fastened to the rock shaft J, which turns in projections on the stands C, C, provided for that purpose as shown in Fig. l. The slide K, is fitted to traverse on the lever I, and is provided with pivots for the end of the connecting rod L, as shown in Fig. l, and the upper end of this connecting rod is hinged to the eye bolt M, in the helve D. The connecting rod L, is made elastic or yielding and consists of ahollow cylindrical shell contained in the spiral spring il. The upper end of this spring acts against a shoulder in the cylinder, and the lower end against the head of the rod I), which passes up through the spring N, into the hinge nut R, "as shown in Fig. 1, thus Aforming an elastic or yielding connecting rod between the lever I, and the helve D, so that the crank carries the hammer and helve up during one half-of its revolution, and with such force that their momentum continues to carry them up, and at the same time compress the spring in the connecting rod, while the crank is making about one fourth of a revolution downward, (or rather upward as it acts on the opposite end of the lever) so, that the hammer when it is oper ated, rises during about three fourths of the revolution of the crank, and descends and strikes the blow during the remaining one fourth. The momentum of the rising hammer and helve compresses the spring in the connecting rod, while the lower part of the rod is descending and adding to the compression of the spring; so that when the spring expands, it draws the hammer and helve down with great force and with an accelerating motion until it strikes the blow.

In order to traverse the slide K, on the lever I, and vary the force of the blows struck by the hammer while it is in operation, I make a rock shaft S, to turn in projections on the stands C, C, and fasten the arm T, to the shaft S, and connect the end of the arm to the connecting rod L by the link U, as shown in the drawing. And the lever V, is fastened to the end of the rock shaft S, so as to be convenient to the man who turns the iron under the hammer, so that by raising the lever V, he moves the slide out on the lever I, and increases the force of the blows, and by depressing the lever V, he diminishes the force of the blows of the hammer; and he cando this easily with one hand, while he turns the iron with the other.

W, is a stand fastened to the base A, and provided with notches to hold the lever V, in such position as may be desired.

To balance the weight of the helve and hammer on the aXis I hinge the rods X, X, to the bed A, and fasten the bar Y, to the helve D, so that the bar will traverse on the rods and apply spiral springs Z, to therods X, to act against the bar and press up the helve; these springs may be made strong enough to balance the helve and hammer, but if they are not made strong enough for that purpose, one or more springs a, may be applied behind the axis, and fastened to the base and the rear end of the helve to pull it down.

By balancing the helve and hammer with springs I believe the hammer is worked with far less power than it could be without being so balanced.

To turn the crank and operate the hammer I apply a loose belt to the pulley Gr, with a lever and friction pulley to tighten the belt more or less and run the hammer at the speed desired or vary the speed as required. I also arrange a brake `to the fly wheel F,

(so as to be operated by the same lever that operates ther friction pulley) to stop the hammer suddenly if required.

With my improvements a hammer may be worked withI great or small power to suit the work being done. That is it may be worked so as to serve the purpose of a hammer much larger, or much smaller, than itself; and do the variety of work that would require three hammers as they are ordinarily constructed. Besides it is believed that a hammer withy my improvements will do a given quantity of work with one fourth of the power required for the common tilt or forge hammers. Y,

I contemplate that the springs which balance the hammer and helve may be arranged onV one or both sides of the aXis, either above or belowV the helve as may be preferred. Also that the elastic connecting rod 'may be applied directly to the crank if preferred that way. And further that the elastic or yielding connecting rod may be used to great advantage in operating hammers or stampers for crushing ores and for other purposes.

I believe I have Vdescribed and represented my improvements in forge hammers son as to enable any person skilled in the art to make and use them. I Will now state what I desire to secure by Letters Patent, to wit.

I claiml. An elastic or yielding connecting rod, constructed as described or in some equivalent manner.

2. An elastic Vor yielding connecting rod or its substantial equivalent, in combination with the vibrating arm or lever that operates it, to work the hammer.

3. Connecting the connecting rod to the arm or lever that operates it, by means of a slide arranged to traverse on said arm, so as to vary the length of the stroke and the force of the blows struck by the hammer while it is in operation and without stopping it.

t. The crank Which operates the hammer in combination with an elastic, or yielding connecting rod.

5. Balancing the helve and hammer by springs arranged on one or both sides of the fulcrum.
